Variables | |
char const | msg_mime_version_1_0 [] |
Protocol version of MIME. | |
MIME headers and multipart messages (RFC 2045).
char * msg_accept_any_dup_one | ( | msg_header_t * | dst, |
msg_header_t const * | src, | ||
char * | b, | ||
isize_t | xtra | ||
) |
Duplicate one msg_accept_any_t object.
isize_t msg_accept_any_dup_xtra | ( | msg_header_t const * | h, |
isize_t | offset | ||
) |
Calculate extra memory used by accept-* headers.
msg_accept_t * msg_accept_match | ( | msg_accept_t const * | a, |
msg_content_type_t const * | c | ||
) |
Check if the Content-Type is Acceptable.
@TODO Content-Type parameters (e.g., charset) are not checked.
int msg_multipart_complete | ( | su_home_t * | home, |
msg_content_type_t * | c, | ||
msg_multipart_t * | mp | ||
) |
Add all missing parts to the multipart.
Add missing components such as boundaries between body parts, separators between body-part headers and data, and close-delimiter after last body-part to the multipart message.
[in,out] | home | home for allocating structures |
[in,out] | c | content-type header for multipart |
[in,out] | mp | pointer to first multipart structure |
0 | when successful |
-1 | upon an error |
msg_multipart_t * msg_multipart_create | ( | su_home_t * | home, |
char const * | content_type, | ||
void const * | data, | ||
isize_t | dlen | ||
) |
Create a part for MIME multipart entity.
The function msg_multipart_create() allocates a new msg_multipart_t object from memory home home. If content_type is non-NULL, it makes a msg_content_type_t header object and adds the header to the msg_multipart_t object. If dlen is nonzero, it allocates a msg_payload_t structure of dlen bytes for the payload of the newly created msg_multipart_t object. If data is non-NULL, it copies the dlen bytes of of data to the payload of the newly created msg_multipart_t object.
msg_multipart_t * msg_multipart_parse | ( | su_home_t * | home, |
msg_content_type_t const * | c, | ||
msg_payload_t * | pl | ||
) |
Parse a MIME multipart.
The function msg_multipart_parse() parses a MIME multipart message. The common syntax of multiparts is described in RFC 2046 (section 7).
[in,out] | home | home for allocating structures |
[in] | c | content-type header for multipart |
[in] | pl | payload structure for multipart |
After parsing, the pl will contain the plain-text preamble (if any).
"--Pekka"
. issize_t msg_multipart_prepare | ( | msg_t * | msg, |
msg_multipart_t * | mp, | ||
int | flags | ||
) |
Encode a multipart.
unsigned msg_q_value | ( | char const * | q | ) |
Calculate Q value.
The function msg_q_value() converts q-value string q to numeric value in range (0..1000). Q values are used, for instance, to describe relative priorities of acceptable Content-Types.
q | q-value string ("1" | "." 1,3DIGIT) |
